INTRODUCTORY SAFETY MESSAGE TO PARENTS

AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE. An ATV handles

differently from other vehicles including motorcycles and cars. A collision or rollover

can occur quickly, even during routine maneuvers such as turning and driving on hills

or over obstacles, if you fail to take proper precautions.

Children differ in skills, physical abilities, and judgement. Some children may not be

able to operate an ATV safely. Parents should supervise their child’s use o f the ATV

at all times. Parents should permit continued use only

if they determine that the child

has the ability and maturity to operate the ATV safely.

Failure to follow the warnings contained in this manual can result in

SERIOUS INJURY or DEATH.

• Read this manual and all labels carefully and follow the operating procedures de-

scribed.

• Never operate an ATV without proper instruction. Take a training course. Riders

should receive training from a certified instru ctor. Contact an authorized Polaris

ATV dealer or call Polaris at 1-800-342-3764 to find out about the training courses

nearest you.

vi

• Always follow the age guidelines for your machine. Youth ATVs are designed and

intended for use by children in two age groups. The Scrambler 50 is for children

not less than 6 years of age. The Scrambler 90 and the Sportsman 90 are for chil-

dren not less than 12 years of age. No children under the age of 16 should ride an

ATV designed and sold for an adult.

the instructional video and taken and passed a Polaris approved riding skill test.
